Non-randomised trial, 2025 # Does drinking soy milk or eating tempeh reduce PMS symptoms? Soy milk significantly reduced PMS symptoms (p = 0.003), but tempeh did not (p = 0.105) in this study. Physical activity was also a strong factor. Early or limited evidence 30 women aged 20-30 in Bekasi, Indonesia with PMS ## What they did 30 women aged 20-30 in Bekasi with PMS were split into groups: some drank soy milk, some ate tempeh, some were control. They consumed their assigned product for 14 days before their period. PMS symptoms were measured before and after. ## What they found Soy milk group had a significant drop in PMS scores (p = 0.003). Tempeh group showed no significant improvement (p = 0.105). No significant difference between the soy milk and tempeh groups (p = 0.818). Physical activity was a strong influence on results (p = 0.042). ## What it means for you Soy milk might help reduce PMS, possibly because of compounds called isoflavones. Tempeh did not help in this study even though it also contains isoflavones. Physical activity matters too. The main limits are the very small sample (only 30 women total), short time period (14 days), and other factors like food intake and stress may have affected results. 30 Women studied p = 0.003 Soy milk reduced PMS symptoms 14 days Duration before menstruation ## About the study Original title The Effect Of Consumption Of Soy Milk And Tempeh In Women Aged 20-30 Years With Premenstrual Syndrome Authors Fillah Fithra Dieny, Azizah Dynda Dwiputri, Aryu Candra Journal Window of Health Jurnal Kesehatan Year 2025 Study design Non-randomised trial Participants 30 What was tested Soy milk and tempeh consumed for 14 days before menstruation Open access Yes Read the paper [doi.org/10.33096/woh.v8i2.729](https://doi.org/10.33096/woh.v8i2.729) ## Topics [Premenstrual syndrome (PMS)](https://niyora.com/research/topics/condition-pms/)[Exercise and yoga](https://niyora.com/research/topics/treatment-exercise/) Research tells you what helps on average.
